We stayed for 4 nights in Freeway Guest House. It's very good experience for us.
The location is convenience. There are 7-11, massage shop, restaurants, bus stop in 5-10 minutes walk way. Big C and BTS stations are just in 15 mins.
The room is big, clean and bright. Room cleaning service and two bottles of water provided everyday. Refrigerator and hair dryer are provided in room. Wifi is fast and stable.
On the 1/F, there are paid laundry room, we washed and dried our clothes in there(have to buy washing powder in the next door 7-11).
Pia is very kind, sent me helpful informations and suggestions about how to go their location, night markets and other good places.
I will stay again if I come Bangkok again. Highly recommended!
